<u>ANSWER</u>

<u>EXPLANATION</u>
The Cartesian equation is

We substitute 


and

This implies that

Let us evaluate the exponents to get:

Factor the RHS to get:

Divide through by r²

Apply the double angle identity

The polar equation then becomes:

 
        
             
        
        
        
Answer: z = 7
Step-by-step explanation:
Step 1: Subtract 4 from both sides
z + 4 - 4 = 11 -4
z = 7
